On‐Surface Synthesis of Bismuth Monolayers through Ice‐Confined Redox Reactions

Advanced Materials, EarlyView.
We report an ice‐confined growth strategy for the synthesis of atomically thin 2D bismuth and related 2D metals. This approach involves rapid freezing of a BiCl3 aqueous solution on an aluminum foil using liquid nitrogen, which triggers interfacial redox reactions between the ice and the aluminum surface.

Membrane Semi‐Permeability and Ion Selectivity in Chemiosmosis: Open Systems Volume Dependence of Electrolyte Chemistry

Advanced Materials Interfaces, EarlyView.
Very small cellular compartments can break electroneutrality and harness proton gradients without active transport structures, whereas larger volumes cannot, underscoring why life's critical energy processes are confined in microscopic spaces. ABSTRACT The effect of pH changes in external ionic solutions on liposomes entrapping non‐permeable weak acid ...

Compound Poisson particle approximation for McKean–Vlasov SDEs

IMA Journal of Numerical Analysis
Abstract We present a comprehensive discretization scheme for linear and nonlinear stochastic differential equations (SDEs) driven by either Brownian motions or $\alpha $-stable processes. Our approach utilizes compound Poisson particle approximations, allowing for simultaneous discretization of both the time and space variables in ...

Mechanically Tunable Mechanochromic Device with Covert‐Overt Structural Color and Modulation of its Transparency

Advanced Materials Interfaces, EarlyView.
This study presents a novel mechanically responsive optical device that modulates light transmission and generates iridescent structural colors under reflection. The optical transition arises from the exposure of nanoparticles upon stretching, which are initially embedded beneath the surface.

Designing Defect Structure and Interfacial Strain in an Epitaxial VN Bilayer Film by Tailoring N Concentration

Advanced Materials Interfaces, EarlyView.
The N concentration in an epitaxial VN bilayer is tailored from overstoichiometric V0.49N0.51 to understoichiometric V0.56N0.44. Based on ab initio, diffraction, and microscopy data, the overstoichiometric V0.49N0.51 layer contains V vacancies, N Frenkel pairs, and a high density of dislocations.

Nonparametric estimation of infinitely divisible distributions based on variational analysis on measures

, 2015
The paper develops new methods of non-parametric estimation a compound Poisson distribution. Such a problem arise, in particular, in the inference of a Levy process recorded at equidistant time intervals.

Lattice Structures for Bone Replacement: The Intersection of Bone Biomechanics, Lattice Design, and Additive Manufacturing

Advanced Materials Technologies, EarlyView.
This review outlines how understanding bone's biology, hierarchical architecture, and mechanical anisotropy informs the design of lattice structures that replicate bone morphology and mechanical behavior. Additive manufacturing enables the fabrication of orthopedic implants that incorporate such structures using a range of engineering materials ...

Random effects compound Poisson model to represent data with extra zeros

, 2009
This paper describes a compound Poisson-based random effects structure for modeling zero-inflated data. Data with large proportion of zeros are found in many fields of applied statistics, for example in ecology when trying to model and predict species ...

Micropillar‐Engineered Hybrid Adhesive Patch for Surface‐Conformable and Directional Adhesion

Advanced Materials Technologies, EarlyView.
This work presents a surface‐conformable hybrid adhesive integrating height‐optimized hexagonal micropillars with open‐rectangular cuts. The micropillars enhance rough‐surface contact and microscale crack arrest, while the cuts guide and reverse interfacial cracks for strong and directional adhesion. The multiscale architecture achieves robust pull‐off

Ductility Tuning via Cluster Network Characteristics of Porous Components

Advanced Materials Technologies, EarlyView.
Network optimization via cluster characteristics induced by interaction of stress concentration is proposed, demonstrating increased cluster size and dispersion in non‐uniform porous components. The optimized structures exhibit, for the first time, that enhanced ductility and damage progression is controllable through zigzag cluster network designed by
